Title: Information recorder
Inventor: YOSHIHARA YOSHIHIKO
IPC: G03B27/50
Filed: 1987-06-30
Abstract: PURPOSE:To prevent a motor from rotating irregularly by varying the number of pulses inputted to a pulse motor according to a signal obtained by a torque variation detecting means. CONSTITUTION:A slit base 13 is scanned and the number of pulses is calculated; when it is judged that the difference of the calculated number of pulses is larger than a constant value, a display part 43 displays a scan defect, the number of pulses which are inputted to the pulse motor 36 from a pulse motor driving circuit 41 during the movement from a stand-by position to a start position is subtracted, and next operation is started. In this case, the moving speeds of scanning mirrors 10 and 11 are also reduced in synchronism with the moving speed of the slit base 13. Consequently, the output torque of the pulse motor 36 is increased to suppress an irregularity of the rotation.

Abstract: PURPOSE:To accurately control the depth of impurity diffusion as well as to prevent the generation of crystal defects for the titled semiconductor device by a method wherein the silica film containing diffused impurities is applied in uniform thickness, and the diffusion depth at the circumferential part of the window for diffusion is restrained to the thickness same as that of the other part or below. CONSTITUTION:The silicon substrate 11, whereon the silica film 14 was applied, is placed in the furnace of approximately 200 deg.C, and the silica film 14 is sintered. Then, a silica film 15 containing diffused impurities is applied on the silica film 14. In this instance, the silica film 15 is applied almost in uniform thickness irrespective of existence or non-existence of a stepping. Subsequently, the silicon substrate 11 is placed in a diffusion furnace, the diffused impurities in the upper silicon film 15 are diffused on the silicon substrate 11 through the lower silica film 14, and a diffusion layer 16 is formed in the substrate 11. When the diffusion layer 16 is formed as above, the depth of diffusion at the circumferential part of the window 13 to be used for diffusion is formed same as that of the other part or, to be more precise, shallower than the other part.

Title: Loading mechanism of tape cassette
Inventor: ASAMI KATSUO
IPC: G11B15/675
Filed: 1984-07-31
Abstract: PURPOSE:To prevent mis-loading of a tape cassette by adopting the constitution that the displacement of a front cover is restricted so as to be hardly opened in excess of a front face opening or over at tape cassette loading by means of a stopper provided to the front opening of a cassette holder. CONSTITUTION:The stopper 12 provided to the front face opening 2a of the cassette holder 2 restricts the displacement in a loading mechanism 11 of the tape cassette so that the front cover 9 is not opened in excess of the front opening 2a or over at loading of the tape cassette 10. Thus, even if the tape cassette 10 is inserted upward incline, the pass contact and engagement of a chamferring part 10a to the front opening 2a of the cassette holder are prevented. In ejecting the loaded tape cassette 3, since the front cover 9 is opened before the cassette holder 2 steps forward up to the most front part, the restriction of the turning by the stopper 12 is not applied and the front cover 9 is opend sufficiently. Thus, mis-loading of the tape cassette is prevented.

Abstract: PURPOSE:To keep off the admission of harmonics from the input side of a magnetron in an effective manner, by installing plural wave absorbers, different in a wave absorbing characteristics each, in a wall-surface group forming a heater box. CONSTITUTION:Plural wave absorber plates 19a, 19b and 19c, different in a characteristic each, are stuck fast to each wall of a heater box 9.

Title: Air conditioner
Inventor: YAMANE MASATAKA
IPC: F24F1/00
Filed: 1984-08-01
Abstract: PURPOSE:To provide an air conditioner which is low in noise, small in low drafting resistance and light in weight by attaching a planar heater to the inner wall surface of the air duct of a fan. CONSTITUTION:A planar heater 9 is attached to the inner wall surface of the air duct unit 5 of a room unit 1 of a separate type air conditioner. When a through flow fan 8 is turned in the direction of arrow A, the air drawn in from an air intake 2 passes over the inner surface of the air duct unit 5 and is discharged from an air outlet 3. As the air passes over the surface of the heater 9 during the process, the air gets heated. Since the planar heater is very thin, it does not adversely affect the drafting characteristics of the through flow fan 8 even though it is attached to the interior of the air duct unit 5. In this manner, it becomes possible to install a heater simply and conveniently without increasing the drafting resistance and noise.

Abstract: PURPOSE:To improve orientation property of crystal of magnetizable element material in the direction for easy magnetization by annealing an ingot of highly magnetizable substance of spin realigning type before it is crushed and powdered. CONSTITUTION:The ingot made from disolved spin realignment type highly magnetic substance is annealed before it is crushed. The annealing of the ingot accelarates the growth of crystal grains and each unit of resulted particle is considered to act like single crystal. As a result, each grain becomes single crystal and is given strong orientation property by being powdered and molded in a magnetic field. This improves alignment of the crystal of the sensitive element material in the orientation for easy magnetization.
